+Status:           Bogus
 Bug Type:         XSLT related
 Operating System: Windows Vista
 PHP Version:      5.2.1
 New Comment:

it's a libxslt issue, if at all, as you correctly realized by yourself.

Please complain there, if you really think, it's a bug.

But you have a 
<template match="node()">
matcher, which also matches to processing-instruction() and comment() 
nodes...

If you change that to <template match="*|text()"> everything works like

expected

Description:
------------
The default (built-in) template for processing instructions and
comments is not implemented in the current version of libxslt. The
template should be as follows:
  <xsl:template match="processing-instruction()|comment()"/>

This is defined in the W3C recommendation
(http://www.w3.org/TR/xslt#built-in-rule).

The files used in the test code can be found here:
  http://scott.trenda.net/xml/php-bug-report/test.php
(source pasted to
"Reproduce Code" section)
  http://scott.trenda.net/xml/php-bug-report/checkerboard.xml
  http://scott.trenda.net/xml/php-bug-report/checkerboard.xsl
  http://scott.trenda.net/xml/php-bug-report/checkerboard2.xsl

This has been reproduced on Windows Vista, running 5.2.1 through IIS7
(ISAPI), and on Linux running 5.1.2 through Apache 2.0
(http://scott.trenda.net/phpinfo.php).

Reproduce code:
---------------
<?php $xslt = new xsltProcessor; ?>
<div>
  <span>Incorrect transformation:</span>
  <div>
    <?php
      $xslt->importStyleSheet(DOMDocument::load("checkerboard.xsl"));
      echo
$xslt->transformToXML(DOMDocument::load("checkerboard.xml"));
    ?>
  </div>
  <span>Correct transformation (built-in stylesheet explicitly defined
in checkerboard2.xsl)</span>
  <div>
    <?php
      $xslt->importStyleSheet(DOMDocument::load("checkerboard2.xsl"));
      echo
$xslt->transformToXML(DOMDocument::load("checkerboard.xml"));
    ?>
  </div>
</div>

Expected result:
----------------
The first example does not have a template defined for processing
instructions and comments; if you view the source, you will see the
xml-stylesheet processing instruction from the source, and the test
comment following it:
<?xml-stylesheet type="text/xsl" href="xslt/checkerboard.xsl"><!--
Testing comment template -->

The second example has the template explicitly defined as per the W3C
Recommendation; its source has neither the xml-stylesheet processing
instruction nor the test comment.

Actual result:
--------------
<div>
  <span>Incorrect transformation:</span>
  <div>
    <?xml-stylesheet type="text/xsl" href="xslt/checkerboard.xsl"><!--
Testing comment template --><html>
